Re: Tube ----- big one (relatively)



Ed,
Thank you for an interesting search.
Grab your Ohmmeter and get back fast to that antique store-pronto.
Machlett is/was a subsidiary of Raytheon. The 5606 is a water-cooled triode. 
The large
terminal on top is the anode + the fitting for the water jacket. The tube 
will handle 10kW
and will operate up to 1.6 mHz. The plate voltage is 14 kV -at- 2 Amps and the 
tungsten filament eats 22 V at 60 A. Does not sound too practical for a TC, 
but if the tube is good it
might be fun to play with if you can light a fire under the filament. But 
here is the best part,
and hold on: A 1972 Richardson Electronics catalog lists the 5606 at $700. I 
would give the guy his 35 bucks even if the tube is dead.

Hi, 
Based on the responses I saw a week or so ago when someone asked a similar
question, it looks like there are a few who could easily answer this.
I was at an "antique" store over the weekend, and saw an intimidating looking
tube.  I never gave much thought to building a tube coil, but this one had an
inspirational look to it.  Then again, I've never been much one for intuition,
so I didn't buy it, pending identification and advice from my fellow list
members (!)  .....
The clear glass part is about 7 or 8 inches tall, with four approx. 1/4 inch
pins on the base.  Then, there is a 9 or 10" long by approx. 2 1/2 inch dia.
rod of copper atop the glass part (or it could be a copper shield/heat sink
around taller glass.. not sure).  I realize that is a pretty weak description,
so, what the heck, here are the details:
MACHLETT ML-5606 --------- it is described (by the store) as a "switching 
tube"
and they are selling it for $35 (u.s.).
I had to ask... I imagine the likelihood of this being useable for a TC is
pretty low... But I would appreciate any responses... 
Thanks,
Ed.
